They are securely adhere to index cards placed inside of descriptive envelopes. The one featuring in red velvet is Joe Louis championship boxer first issue 1933 29 cent stamp. The one featured in blue velvet is a 1914 inverted Jenny US postal service 24 cent stamp both encased in 22 karat gold! Very rare very hard to come by maybe the only ones ever seen from this collection, I am asking $75 a piece or 125 for both.
